If there is no correspondence with the previous
measurement:
If it is not a floating system, the measurement will supply the
following results: L1 with safety earthing = 0 V AC and N with
safety earthing = 230 V AC. In this case, the current source
must be adjusted so the output becomes floating when
compared to the safety earthing. This can be achieved by:
Interrupting the earth wire that connects one of the outputs
(L1 or N) with the housing.
The inverter housing and isometer must, however, be
connected to the chassis of the vehicle.
Again carry out the above measurements to check.
Connection
The isometer must be installed between the output of the
inverter/generator and the consumers. Always connect the
isometer directly on to the inverter/generator. Therefore, for
any other peripherals such as, for example, a switch box for an
inverter/line voltage.
The input cable of the isometer can be connected to the power
point of the inverter/generator through the plug. If the
relevant current source has a fixed cable output, there are two
options. The safety earthing plug of the isometer can be cut
and the output cable of the inverter/generator can be
connected directly to the input cable of the isometer. Or install
a power point on the output cable of the inverter/generator
and connect the input cable of the isometer to this.
The ISO 230 output type consists of a fixed cable. A power
point can be installed on this if required. The ISO 230PP type
has a power point as output to which the consumer(s) can be
connected to directly.
Install the cabling correctly against the chassis or plating.
Putting into operation
Once the isometer has been connected and the connections
have been checked, the input voltage of the floating system
can be activated. The isometer will perform a self-test (see the
